Problems solved by technology

The eutrophication of the water body will cause the pH value to drop, and the pH value drop will not only lead to an increase in sulfide, but also an increase in the activity of heavy metals, which leads to an increased risk of diseases such as bone pain
At present, most aquaculture farms and rivers that require water quality treatment are not connected to the sewage tr

Example Embodiment

[0022] Preferably, a method for preparing a purifying agent for aquaculture and river deodorization includes the following steps:

[0023] Step 1: Pour sodium hydroxide into the water and mix it into a sodium hydroxide solution. Adjust the pH value of the sodium hydroxide solution to 9.3-9.5; because the highest pH value of the magnesium hydroxide solution will not exceed 9, step one is adjusted first The preparation of sodium hydroxide solution is a water purifying agent only in a strong alkaline environment.

[0024] Step 2: Divide the sodium hydroxide solution in step 1 into two parts;

[0025] Step 3: Put magnesium hydroxide and sodium hydrogen phosphate into two sodium hydroxide solutions, and let stand separately;

[0026] Step 4: Mix the sodium hydroxide solution with magnesium hydroxide added in Step 3 and the sodium hydroxide solution with sodium hydrogen phosphate added in the same container to obtain a purifying agent for aquaculture and river deodorization.

Abstract

The invention provides a cleaning agent for aquaculture and river channel deodorization. The cleaning agent is a solid-liquid mixture and comprises the following raw materials in parts by weight: 16-26 parts of magnesium hydrate, 5-10 parts of dibasic sodium phosphate and 20-50 parts of water. According to the cleaning agent for aquaculture and river channel deodorization and a preparation methodof the cleaning agent, the magnesium hydrate is adopted as a main component of the cleaning agent, the content of hydrogen sulfide in culture water and river channels can be effectively reduced, and avery good improvement effect on too low pH values eutrophication of water can be achieved. The cleaning agent is reasonable in preparation method material and step, low in cost and applicable to large-scale application.

Description

technical field [0001] The invention relates to a water purifying agent, in particular to a purifying agent for aquaculture and river course deodorization and a preparation method thereof. Background technique [0002] In recent years, intensive aquaculture has developed rapidly at home and abroad, especially in my country. Its aquaculture production has accounted for about 2 / 3 of the world's aquaculture production. Water resources are consumed, and the feed residues put in during the aquaculture process and the pollutants formed by the excrement of fish, shrimp, and crabs have polluted the water body and the bottom mud of the pond, etc., making the aquaculture water body increasingly eutrophic and affecting the surrounding waters. The environment and ecology are causing more and more harm. [0003] In addition, the pH value in water quality is also an important pollution-related factor. The eutrophication of the water body will cause the pH value to drop, and the pH value d...
